Benefits of technology

The invention provides a hinge module that improves friction and durability for an electronic device. By increasing the friction surface area and decreasing the contact force, the module can provide a larger friction force without increasing the size of the hinge. This solves problems of large locking force and durability for hinge modules with identical size limitations.

Problems solved by technology

However, the washer with too large diameter will increase a total diameter of the shaft and too many washers will increase an axial thickness of the shaft.
Moreover, the components are complicated and have too many contact surfaces, such that the friction force of the shaft may decay and become unstable after being used for a certain period of time.

Abstract

A hinge module includes a plurality of discs, a plurality of friction plates and a restraining member. The discs are eccentrically connected to each other. Each of the friction plates has a circular hole, each of the friction plates is rotatably disposed on one of the discs through the circular hole, and the friction plates contact each other. The restraining member is disposed on the friction plates.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The invention relates to a hinge module and an electronic device for providing friction force in rotation direction and, more particularly, to a hinge module capable of improving frictional locking force and durability and an electronic device equipped with the hinge module.2. Description of the Prior Art[0002]A type of hinge is used to rotatably connect two components and allows the components to freely rotate with respect to each other according to some purposes, such as a hinge for a door or a window. Another type of hinge is used to rotatably connect two components and provides stable dynamic or static friction force in rotation direction, wherein this type of hinge may be called friction hinge. The friction hinge generates friction force by internal structures thereof, such that the friction hinge can provide a dynamic friction force in rotation direction when a device is pushed to rotate by a user. Furthermore, the fric...
